im sorry. if hes ur brother....he shouldnt say those things to u....if he continues to do this just talk to him about it.

"But yet bạn share the same blood?"

I would of punch't him bởi now at at least hit him with a batt

If I were bạn
I'd slap him
__________
oh no

well i m youngest of all but still i think if i would be at ur place i would kick him hard and if he again dare to spak that i would sit with him and say that get ready and then would give him a huge ose of slaps and kicks after that i would tell him that it was wrong and if u wanna hv thêm speak again... just this much.....

This should get bạn by. When he's annoying you, think about this:

..._...|..__________ __________
....../ `---___________---- _____|]==============Felix
...../_==o;;;;;;;;__ _____.:/
.....), ---.(_(__) /
....// (..) ), ----"
...//___//
..//___//
.//___//


Don't actually do it.

I don't have any siblings so I can't really know how it is to have a brother, but if my little cousin would say that to me I'd start fake-crying really really hard and put on a nervous-breakdown-act. That'll probably scare him off and he'll hopefully stop saying those things :P.
